The "딱 1주일 다이어트 습관" app, developed by Appsfabrica, is a weight loss program that helps users change their habits to lose weight and keep it off. Unlike most fad diets that rely on calorie counting or intermittent fasting, this app focuses on changing daily habits to promote a healthier lifestyle. The app features a diet diary and a weight loss magazine, which provide users with advice and information on how to lose weight and keep it off. The diary allows users to track their daily meals, check their BMI, monitor their water intake, and keep track of their exercise routine. The magazine includes tips and tricks on healthy eating, exercise, and how to stay motivated during weight loss. The app is available for free on Android.
